[HANG] Deadlock in MBE with 24-fixes

Description

Upgraded to the lastest 24-fixes a few weeks ago and have had some deadlocks on the master BE since. Been happening quite often lately, twice in 2 days. My MBE runs on it's own server, I have 2 other machines with slave BEs and FEs on them.

Haven't been able to determine what actions (recordings start/stop etc) are happening when it occurs as I'm always at work. Backtraces from the last 2 deadlocks are attached.

Only recent upgrade I can think of is moving to an SSD for the MBE OS and myth DB. Running on gentoo.

Had 2 more deadlocks occur in the past 2 days. One of them occurred after my hdpvr recording failed on a slave backend. Backtrace and mysql process list attached

This hasn't occurred in the past few months. Think it was fixed by one of the deadlock patches in 24 fixes.
